Textures made of things created by nature, including sand textures, are popular and useful resources for graphic designers. They can be used to add a tactile feel and depth to the design and are available in many variations. Whether you need textures for e.g. creating web backgrounds, or as an overlay in photo manipulation, a sand texture can often be used in combination with other related textures. I’m sure you will find some water textures, paper textures or wood textures useful, as well. If you want to add a solid, sturdy or a somewhat industrial look, you can use a glossy, rusty, or a grungy metal texture along with a sand texture on your designs.
Meanwhile, if you are looking for a texture that you can use to add a grainy feel, or if you want to create a photo manipulation involving a beach, etc. you will find this sand texture collection useful. These sand textures are all free so you can use them without spending anything. Just be sure to credit the authors of these works where credit is required or as requested by them. Enjoy!
